# Line 1 | Line 1
1 + IBX Change Log  version (2.3-5 Build 12212) Fri, 17 Jul 2020 15:24:08 +0100
2 +
3 + 1.  TIBStringField: when a string value is read from a dataset buffer, if the
4 +    number of UTF8 characters exceeds the string size then string is truncated
5 +    to the maximum string size. This is  usually a problem with fixed width columns
6 +    right padded with white space.
7 +
8 + 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
9 +    If SQLFiltered is set then when a dataset is opened, each line in the
10 +    SQLFilterParams property is assumed to be a SQL condition clause and
11 +    ANDed into the Where clause of the SQL Select statement provided as a
12 +    dataset property. Each such SQL condition thus acts as an additional filter
13 +    on the dataset. (Not yet tested)
14 +
15 + 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
16 +    side filters).
17 +
18 + IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
19 +
20 + 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
21 +    not SQL Identifiers are now supported.
22 +
23 + 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
24 +    passed to the Firebird engine for execution.
25 +
26 + 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
27 +    is made to scroll back.
28 +
29 + 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
30 +
31 + 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
32 +   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
33 +
34 + 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
35 +   validated. If no match is found in the list of field names and the database has
36 +   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
37 +   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
38 +
39 + 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
40 +   with fpc 3.2.
41 +
42 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
43 +
44 +
45 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
46 +   and is used to override the default settings in the client side "firebird.conf" This
47 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
48 +   Each line of the string list should be a setting in the same format as "firebird.conf".
49 +   For example "WireCompression = true" in order to request wire compression on the client side.
50 +
51 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
52 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
53 +   also require a compatible setting in the server side "firebird.conf". For example
54 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
55 +   compression to be used.
56 +
57 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
58 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
59 +   ibx/examples/dbinfo for examples of how to display this information.
60 +
61 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
62 +   is a "convenience" property. If set the "WireCompression=true" is added to the
63 +   ConfigOverrides. If unchecked then this setting is removed.
64 +
65 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
66 +   not "INT64".
67 +
68 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
69 +   These are:
70 +    property TimestampFormat: string;
71 +    property DateFormat: string;
72 +    property TimeFormat: string;
73 +
74 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
75 +   DATETIME and TIME. The format strings use the standard FPC date/time format
76 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
77 +
78 +   If any of the above properties are set to an empty string, then the locale default
79 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
80 +   locale default is extended by appending '.zzz' to include milliseconds.
81 +
82 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
83 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
84 +
85 + 5. New published property for TIBCSVDataOut:
86 +     property QuoteStrings: boolean (default true)
87 +
88 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
89 +   used to delimit each and every string in the output.
90 +
91 + 6. New published properties for TIBCSVDataOut:
92 +    property FieldSeparator: string;
93 +    property HeaderSeparator: string;
94 +
95 +   Respectively, these provide the separator character(s) used to separate fields
96 +   in data and header rows. Both default to ','.
97 +
98 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
99 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
100 +    property OnFormatTextString;
101 +
102 +   This event handler can be used to process text strings before they are included
103 +   in the output e.g. to replace unprintable characters with alternative strings.
104 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
105 +
106 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
107 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
108 +   and without raising and exception if it does not.
109 +
110 + 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
111 +   consistency with SQL queries.
112 +
113 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
114 +    When true, SQL statement parameter names are parsed case sensitive. Note for
115 +    TIBDataSet only applies to Select query.
116 +
117 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
118 +    an IDE exception.
119 +
120 + 12. LocalDBSupport: initial database creation should now work correctly
121 +    when the schema source is an sql file.
122 +
123 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
124 +    when defined, this handler will be called by the internal TIBXScript during
125 +    initial database creation when the schema source is an sql file and may be used
126 +    to provide a visual indication of progress in console mode.
127 +
128 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
129 +    to true while a new local database is being created and its schema populated.
130 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
131 +    when the database is disconnected/connected during the create DB procedure.
132 +
133 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
134 +    are now always ignored and replaced by the user name and password provided as
135 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
136 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
137 +    completely ignored if this property is true.
138 +
139 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
140 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
141 +    ImageIndex and SelectImageIndex values on AddNode.
142 +
143 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
144 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
145 +    the same database connection.
146 +
147 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
148 +    if provided, this should be an conditional SQL expression suitable for
149 +    including in an SQL Select statement "where" clause. If non-empty and the
150 +    "Filtered" property is true then the SQL expression provided as the value of
151 +    the "Filter" property is "ANDed" with any existing condition statement
152 +    in the SQL statement's "Where" clause.
153 +
154 +    If the "Filter" property is set at run time, the "Filtered" property is true
155 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
156 +
157 +    The "Filter" condition may include IBX style parameters. In which case, their
158 +    value must be set by the dataset's "OnBeforeOpen" event handler.
159 +
160 +    This is a public property for TIBDataSet and TIBQuery query and intended for
161 +    use at run time.
162 +
163 +    Note: The property is a published property of TIBTable. The TIBTable functionality
164 +    is unaffected by this change.
165 +
166 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
167 +
168 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
169 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
170 +   mode apps.
171 +
172 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
173 +   statement. This avoids problems if "Execute Block" is used as the Query.
174 +
175 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
176 +   internal SQL tokeniser routines.
177 +
178 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
179 +   as a select statement, with or without CTEs.
180 +
181 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
182 +
183 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
184 +   internal SQL tokeniser routines.
185 +
186 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
187 +    being raised for valid set statements processed by a data formatter.
188 +
189 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
190 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
191 +   the path of the Firebird Library used by the database/services connection.
192 +
193 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
194 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
195 +   services connection.
196 +
197 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
198 +   or param name is not a valid SQL identifier.
199 +
200 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
201 +    view of whether the text box should be editable when no DataSource is specified.
202 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
203 +    ReadOnly is false, the text box is editable when no DataSource is specified.
204 +
205 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
206 +    the FBLIB environment variable. If you do not want to permit this then you
207 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
208 +    this setting.
209 +
210 + IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
211 +
212 + 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
213 +   Utf8EscapeControlChars
214 +
215 + IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
216 +
217 + IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
218 + all previous copies of the IBX source code tree before installing this release.
219 +
220 + The IBX packages used by most users have not changed, with one exception. The
221 + IBServices unit has been moved to the package iblegacyServices.lpk. To continue
222 + to use the IBServices unit in your applications, please add the iblegacyServices
223 + to the list of dependencies. To do this, open the Project Inspector and select
224 + Add->New Requirement and select "ibLegacyServices" from the list of available
225 + packages.
226 +
227 + 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
228 +   the IBServices unit providing what is intended to be a clearer and easier to
229 +   use set of IB Services components. See Chapter 10 of the IBX User Guide for
230 +   more information and the guide to "Firebird Service Management Using IBX".
231 +   As indicated above, the legacy services components are still available and
232 +   provided in a separate package. There is no need to update working applications
233 +   using the older versions except for an additional package dependency.
234 +
235 + 2. The IBX packages and source code tree have been re-organised in an attempt to
236 +   finally get rid of the "duplicate ppu" warnings. This re-organisation should
237 +   not affect existing users. Section 2.3 of the IBX User Guide describes the
238 +   new set of IBX packages.
239 +
240 + 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
241 +   updated to use the new Services API components.
242 +
243 + 4. The iblocal package has been updated to use the new Services API components.
244 +
245 + 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
246 +   TIBXSecurityService. It had been wrongly classified in the previous version
247 +   as a per database configuration item. It is global to a server and hence
248 +   correctly positioned as part of the Security Package. In the DBAdmin example,
249 +   the setting has moved to the mappings page.
250 +
251 + 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
252 +   are ignored.
253 +
254 + 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
255 +   closed before the database is dropped. Before and After Disconnect event handlers
256 +   are also fired.
257 +
258 + 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
259 +   is started and not just the first time.
260 +
261 + 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
262 +   depenendency with comp type.
263 +
264 + 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
265 +
266 + 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
267 +    then this is recognised and not ignored.
268 +
269 + 12. TIBDataSet, TIBQuery, TIBTable: additions:
270 +    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
271 +    function GetPerfStatistics(var stats: TPerfCounters): boolean;
272 +    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
273 +
274 +    GetRowsAffected returns the affected row counts from the last insert/update/delete
275 +    if EnableStatistics = true then GetPerfStatistics returns the current stats
276 +    counters for the select query. Note: stats accumulate after each fetch from
277 +    the database. To get total query cost after open, call the "Last" method
278 +    and then GetPerfStatistics.
279 +
280 +    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
281 +
282 + 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
283 +    in parenthesises.
284 +
285 + 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
286 +    SQL identifiers are always delimited by double quotes. If false, then they are
287 +    only delimited if the identifier is a reserved word, contains lower case or special
288 +    characters. Set this property to true to retain previous behaviour.
289 +
290 + 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
291 +    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
292 +
293 + 16. TIBDataSet, TIBQuery, TIBTable: addition:
294 +       property MasterDetailDelay: integer {defaults to zero}
295 +
296 +    When non-zero and the dataset is a detail table referencing a master table
297 +    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
298 +    then a synchronisation delay is added (in milliseconds) between the master
299 +    row changing and the detail dataset being re-opened. If the master dataset
300 +    is scrolled before the delay expires then the delay is reset. This can be used
301 +    to avoid performance overheads when scrolling through a large master dataset.
302 +
303 +    Note: uses fptimer and hence requires a thread manager. Under Linux the
304 +    chreads unit must be included in your project. TTimer is not used in order
305 +    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
306 +
307 + 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
308 +    with Extract Option eoDatabase.
309 +
310 + 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
311 +    When a deLayoutChanged event is reported on the ListSource dataset, the
312 +    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
313 +    relationship with the control's datasource (master).
314 +
315 + 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
316 +
317 + 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
318 +    stubs. Pedantic fix really, as procedures output in dependency order anyway.
319 +
320 + 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
321 +    DDL (Firebird 3 and later only).
322 +
323 + 22. TIBLookupComboBox Autocomplete Fixes:
324 +    i. Only appended text is now selected after autocomplete.
325 +    ii. Uppercase keys no longer ignored for autocomplete.
326 +    iii. Retain Prefix case is now honoured correctly.
327 +    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
328 +        before autocomplete performed. i.e. behaviour now the same as when
329 +        no DataSource assigned.
330 +
331 + 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
332 +    between SQL statements.
333 +
334 + 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
335 +    ObjectNames are converted to upper case before matching against metadata object
336 +    names, unless the objectname is delimited by double quotes, in which case, the
337 +    double quotes are removed and the remaining string is used (unmodified) to match
338 +    against the metadata object name.
339 +
340 +    If true then the ObjectName is used as is without modification and matched
341 +    against the metadata object name. No attempt is made to remove double quotes.
342 +
343 + 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
344 +    with eoTrigger, these extract types can be used to select only Database Triggers,
345 +    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
346 +
347 + 26. TIBXScript: If an exception occurs during the processing of a statement, the
348 +    statement separate character is now reset to the default (';').
349 +
350 + 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
351 +
352 + 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
353 +    a commit or reconnect statement and instead activated only when next SQL statement
354 +    is executed.
355 +
356 + 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
357 +
358 + 30. TIBXScript: case insensitive regex now used when matching statements instead of
359 +    converting statement to upper case.
360 +
361 + 31. TIBExtract: metadata comments now supported. New published property
362 +    IncludeMetaDataComments (default true). If true then metadata comments included
363 +    in extracted DDL. New Extract Object member eoComments. This may be used with
364 +    ExtractObject method to list all metadata comments.
365 +
366 + 32. TIBExtract: ListObjectNames method added.
367 +
368 + 33. Updated Database component editor to support additional connection string
369 +    types.
370 +
371 + IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
372 +
373 + NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
374 + AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
375 + RELEASE.
376 +
377 + NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
378 +
379 + 1. IBExtract: Identity columns - add additional check for null column for generator name.
380 +
381 + 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
382 +   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
383 +   information). However, this is also a very useful mechanism for returning updated computed by
384 +   column values. Values returned as a result of executing an Insert or Update statement
385 +   replace existing values in the current row for each corresponding column.
386 +
387 +   Previously, if a dataset's select query included read only (computed by) fields then
388 +   an automatic row refresh was performed after an insert or update query had been processed,
389 +   irrespective of the setting of the "ForcedUpdates" property. This has changed such
390 +   that an automatic refresh is no longer performed if an insert or update query contains
391 +   a returning clause that updates one or more fields on the current row. A full row
392 +   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
393 +   field values and the select query contains read only fields. Use of Insert/update
394 +   returning should be significantly more efficient than executing a refresh query.
395 +
396 +   This behaviour change is intended to be backwards compatible and there should be no need to change
397 +   existing programs, other than to improve performance by using the new capability.
398 +
399 + 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
400 +   they are called when the dataset row is being deleted, there is no value in
401 +   updating the current record from the query result. Instead, a new event handler
402 +   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
403 +   an OnDeleteReturning event handler is provided then it is called with the IResults returned
404 +   by the query. The event handler can then interrogate the query results and
405 +   perform whatever action is necessary. For example to confirm, to the user,
406 +   the deletion of a row with the returned values.
407 +
408 + 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
409 +   any Computed By or Identity Columns. The IBTables example has been updated to
410 +   illustrate the computation of the employee Full Name on update.
411 +
412 + 5. TIBTable: The GeneratorField property is now published.
413 +
414 + 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
415 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
416 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
417 +   each Identity column after the insert is executed.
418 +
419 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
420 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
421 +   Insert..Returning clause.
422 +
423 + 8. TIBGenerator: small performance improvement by not preparing query each time
424 +   a new value is generated.
425 +
426 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
427 +
428 + 10. Property editors will now sync table name to a System Table when "Include System
429 +    Tables" is selected and the query is for a System Table.
430 +
431 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
432 +    values are no longer converted to milliseconds from TDateTime and then back again
433 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
434 +
435 + 12. Property Editors handling of Stored Procedures.
436 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
437 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
438 +      query).
439 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
440 +
441 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
442 +    can be used to select a package. If non-empty, the stored procedure name is
443 +    expected to be a stored procedure defined in the specified package and the
444 +    generated SQL will be as required for a stored procedure located in a package.
445 +
446 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
447 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
448 +    which a stored procedure can be selected. With no package name selected, non-package
449 +    stored procedures are listed.
450 +
451 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
452 +    for password on reconnect.
453 +
454 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
455 +    and character set name.
456 +
457 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
458 +    DB info lookups"
459 +
460 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
461 +
462 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
463 +
464 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
465 +    parameters. This stops an exception being raised when the field cannot be
466 +    located in the record buffer.
467 +
468 + 21. Property Editors now automatically include System Tables when opened and when the query table
469 +    is a System Table.
470 +
471 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
472 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
473 +
474 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
475 +    add the SPB item isc_spb_expected_db. This names a database using
476 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
477 +    database. examples/services re-written to illustrate use of "expected_db".
478 +
479 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
480 +    This avoids truncated backups when the server returns a timeout (busy) response.
481 +
482 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
483 +
484 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
485 +    databasenames. These are respectively expanded to the local system's temp directory
486 +    (including trailing delimiter) or to a prescribed data directory (including
487 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
488 +    in the user's home directory. The hidden directory name is either the string returned
489 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
490 +    Under Windows, the directory is the same as the Data Directory as decribed
491 +    above but instead prefixed by the User's application data path. These may be
492 +    used to improve application portability for Personal Databases.
493 +
494 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
495 +    this has not worked for a long time and is not useful either. FieldDefs should be
496 +    managed using the Fields Editor as with any other dataset. To access the fields
497 +    editor for a TIBTable component, double click on the component. The fields editor
498 +    is then displayed.
499 +
500 + 28. TIBDatabaseInfo: new properties/function
501 +     * DateDBCreated (returns date/time database created)
502 +     * TransactionCount (returns no. of active transactions)
503 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
504 +     * PagesFree (Firebird 3 or later)
505 +     * PagesUsed (Firebird 3 or later)
506 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
507 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
508 +
509 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
510 +
511 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
512 +
513 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
514 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
515 +
516 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
517 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
518 +    firing during backup and restore.
519 +
520 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
521 +    for verbose output using the new property "StatisticsRequested".
522 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
523 +
524 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
525 +
526 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
527 +    palette. This uses the online validation feature added in Firebird 2.5. The
528 +    services's properties enable inclusion/exclusion of tables and indexes using
529 +    regular expressions. See.
530 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
531 +
532 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
533 +    option on a database.
534 +
535 + 37. TIBCustomService: Assign method implemented to allow copying of service login
536 +    context between service API components. "Detach" method now only detaches
537 +    service when last reference to the service interface detaches. Tidy up of
538 +    code for SetActive and Attach methods including password hiding.
539 +
540 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
541 +    and used to determine the auth method and protocol used for the connection.
542 +
543 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
544 +    a Create Database Statement generated by IBX.
545 +
546 + 40. All IBServices now have an additional published property "PortNo". This may
547 +    be set to a non-standard port number when necessary. If zero then the default
548 +    port number is used.
549 +
550 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
551 +    and not just the mouse.
552 +
553 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
554 +
555 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
556 +    image index and selected image index for each node to be set from a database field.
557 +
558 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
559 +    then database schema includes grants to all users. If not present then the
560 +    only user grants included are those to User PUBLIC.
561 +
562 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
563 +    and child nodes in dataset.
564 +
565 +
566 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
567 +
568 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
569 +   changes.
570 +
571 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
572 +   Bug could result in truncated multi-byte character set values.
573 +
574 + 3. Changes consequential on moving fbintf character set utility functions from
575 +   IFirebirdAPI to IAttachment.
576 +
577 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
578 +
579 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
580 +   results in autocomplete ignoring prefix text.
581 +
582 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
583 +   entering a new name into the text box.
584 +
585 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
586 +   Firebird rather than recomputing it.
587 +
588 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
589 +   screen centre. Previously some were "poDesigned" which may be inappropriate
590 +   for multi monitor desktops.
591 +
592 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
593 +
594 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
595 +    a transaction and always reset the object.
596 +
597 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
598 +
599 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
600 +
601 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
602 +    to a gbak format archive.
603 +
604 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
605 +
606 + 16. IBLocaldb: Drop database if error creating an empty database.
607 +
608 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
609 +    unless selected node not in current dataset.
610 +
611 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
612 +    to TIBCustomService, and IBlocalDB code tidy up.
613 +
614 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
615 +    behaviour due to uninitialised variable.
616 +
617 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
618 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
619 +
620 + 21. IBSQL: When Database changed ensure that all resources are freed.
621 +
622 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
623 +
624 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
625 +    * Line Wrap on SQL Token boundaries (on user command)
626 +    * auto-complete table names in drop down list of table names
627 +    * Double click on tablename or field name adds to SQL text
628 +
629 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
630 +
631 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
632 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
633 +    workaround for a problem in fpc 3.0.4 win64).
634 +
635 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
636 +
637 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
638 +
639 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
640 +
641 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
642 +   include remote system name.
643 +
644 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
645 +   tables when data included in output.
646 +
647 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
648 +   and timing information to be written to stdout. This may be used to locate
649 +   performance bottlenecks.
650 +
651 + 4. SQLParser: only call "OnChanging" event handler when value is different.
652 +
653 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
654 +
655 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
656 +   that BindFields is called when the query is next activated. Avoids FieldName
657 +   not found error.
658 +
659 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
660 +   purpose and allows the programmer to define any action they want for Update, Insert
661 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
662 +   filtering of updates, or use of statements such as Grant or Revoke instead of
663 +   normal DML. See User Manual for more information.
664 +
665 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
666 +
667 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
668 +
669 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
670 +
671 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
672 +   hexadecimal notation.
673 +
674 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
675 +   using a simple XML format.
676 +
677 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
678 +   grants to these objects.
679 +
680 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
681 +   dependency problems restoring complex databases.
682 +
683 + 7. TIBXScript: This component has been restructured to allow for the processing of
684 +   embedded XML in INSERT statements and to support interactive sources in addition
685 +   to non-interactive data sources such as files.
686 +
687 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
688 +
689 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
690 +   SET SQL DIALECT
691 +   SET TERM
692 +   SET AUTODDL
693 +   SET BAIL
694 +   SET ECHO
695 +   SET COUNT
696 +   SET STATS
697 +   SET NAMES <character set>
698 +
699 + 10. IBVersion unit added to hold current IBX Version Number information.
700 +
701 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
702 +    and domain definitions.
703 +
704 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
705 +    fully supported.
706 +
707 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
708 +
709 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
710 +
711 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
712 +
713 + See also doc/IBX4LazarusGuide.pdf for important information on
714 + upgrading to IBX2.
715 +
716 + 1. Size property of TIBStringField is now the width in characters of the field
717 +   and not the byte length. This applies only to multi-byte character sets such
718 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
719 +   code is not recognised as a bug and hence this change to align the behaviour.
720 +   The TStringField change is expected in fpc 3.2.0.
721 +
722 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
723 +   true (default) then Size property value saved in the lfm is ignored. Size is
724 +   always set from the dynamic information read from the database. It is unclear
725 +   why anyone would want to override this and set Size to false.
726 +
727 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
728 +   block.
729 +
730 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
731 +   exist when an attempt is made to connect to it (run time only) then an attempt
732 +   is made to create the database.
733 +
734 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
735 +   has been successfully created as a result of a call to CreateDatabase or when
736 +   creating a database after it was found not to exist.
737 +
738 + 6.  DBControlGrid: a race condition could result in the wrong row image being
739 +    written to the cache. This has been avoided by a trip round the message
740 +    loop before rendering the row image.
741 +
742 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
743 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
744 +    known to risk corrupt rendering of row images when the control is first
745 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
746 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
747 +
748 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
749 +    a TDateEdit control located on an editor panel.
750 +
751 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
752 +
753 + 10. DBControlGrid: Removed memory leak when updating rows.
754 +
755 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
756 +
757 + IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
758 +
759 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
760 +   when target codepage is CP_NONE. This is a workaround for
761 +   http://bugs.freepascal.org/view.php?id=30622.
762 +
763 + 2. DBLog option removed from TIBStatisticalService - not supported by server
764 +   since Firebird 1.5.
765 +
766 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
767 +   similar.
768 +
769 + 4. IBCodePage: updated mapping between codepages and character id.
770 +
771 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
772 +   Firebird. Character sets with a char width of two are not UTF16.
773 +
774 + 6. Strings received from the database are now always transliterated into UTF8
775 +   regardless of the database character set or connection character set. This
776 +   is for compatibility with the LCL.
777 +
778 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
779 +
780 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
781 +   read in an entire blob just to get the size of the blob. General performance
782 +   improvement when opening datasets containing blobs.
783 +
784 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
785 +
786 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
787 +   is now used.
788 +
789 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
790 +   determined.
791 +
792 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
793 +
794 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
795 +   lazarus 1.6.0
796 +
797 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
798 +   compilation error.
799 +
800 + IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
801 +
802 + 1. No character set specified for connection: when a text blob is retrieved, the
803 +  character set is determined by looking up the native character set using then
804 +  Firebird API. Otherwise a text mode blob is assumed to have the same character
805 +  set as the connection.
806 +
807 + 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
808 +   for Login Dialog returing a change to the database path.
809 +
810 + 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
811 +   to be changed from that given in the TIBDatabase/TIBServer component and for the
812 +   entered value to be saved on a project specific basis (design time only).
813 +
814 + 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
815 +   column fieldname. If they are the same then it is acts as a look up for the KeyValue
816 +   Otherwise, it sets the column text to the selected ListField Value.
817 +
818 + 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
819 +   column width.
820 +
821 + 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
822 +   and a case insensitive search is requested.
823 +
824 + 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
825 +   or column ListSource.
826 +
827 + 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
828 +   unprepare) when closing and the text has not changed.
829 +
830 + 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
831 +   Less likely to cause a cursor re-use error on Windows.
832 +
833 + 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
834 +   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
835 +
836 + 11. TIBTreeView: Guard against nil destination on record changed
837 +
838 + 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
839 +    string type with the code page set to reflect the returned field encoding after
840 +    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
841 +    earlier versions.
842 +
843 + 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
844 +    will now result in transliteration to the code page specified for the Firebird driver
845 +    if the assigned string has a different code page. FPC 3.0.0 onwards only.
846 +
847 + 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
848 +    is ignored and the lc_ctype value, when the database is opened, is set to align with
849 +    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
850 +    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
851 +    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
852 +    the GETACP is used to determine the Windows code page.
853 +
854 + 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
855 +    name used as the lc_ctype when the database was opened. Only valid while the
856 +    Database is connected.
857 +
858 + 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
859 +    id that corresponds to the DefaultCharSetName.

862 +
863 + 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
864 +   path is given and database attach fails due to access permission issues on the
865 +   temp directory or security database, then the attach is retried with "localhost:"
866 +   prefixing the databasename. This should avoid problems when the database has to
867 +   be accessed by a local (e.g. classic) server and libfbembed is used.
868 +
869 + 2. Windows: revised search order for Firebird DLL:
870 +     i.   The Firebird Embedded Server in the application Directory.
871 +     ii.  If the FIREBIRD environment variable is set then the directory this
872 +          points to is searched for the FB Client DLL and then then underlying
873 +          "bin" directory.
874 +     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
875 +          is used to locate the Firebird installation directory and the underlying
876 +          "bin" directory is searched for the FB Client DLL.
877 +     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
878 +          are searched for the FB Client DLL.
879 +     v.   The PATH Environment variable is used to search for the FB Client DLL.
880 +     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
881 +
882 + 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
883 +   See doc/readme.scriptengine and example applications.
884 +
885 + 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
886 +   simplify the use of the embedded firebird server on both Linux and Windows platforms.
887 +   See dpc/readme.localdatabase and example applications.
888 +
889 + 5. IBDynamicGrid: Reordering on column header click should now also work for
890 +   dynamic columns.
891 +
892 + 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
893 +   between incrementing/decrementing the lock count and signalling the event.

896  
897 + 1.3.2 was never formally released and only made available as beta copies.
898 +
899   1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
900  
901   2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column

917  
918   7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
919     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
920 <   to be determined at runtime.
920 >   to be determined at runtime. See doc/readme.charactersets.html.
921  
922   8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
923 <   TWideStringField. This field type is used with the character size reported by Firebird is two.
923 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
924  
925   9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
926     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
927 <   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField).
927 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
928  
929     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
930     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
